The 57-year-old man was arrested at his home in Surrey at 6.30am on Thursday on suspicion of misconduct in a public office, according to Scotland Yard.
The man is now being questioned at a London police station and his home searched. The arrest occurred after News Corp's own internal inquiry into hacking handed information to police.
This was the 27th arrest under Operation Elvedon, the Met Police probe into alleged corrupt payments to officials by journalists. It is running alongside the Operation Weeting investigation into phone hacking.
Meanwhile, Rupert Murdoch's News Corp is facing more headaches in the US after a senate committee contacted a UK public inquiry to see if the media giant may have broken American laws.
Jay Rockerfeller, the chairman of the Senate committee on commerce, science and transportation, has contacted Lord Justice Leveson's British judicial inquiry into press ethics, requesting information on any evidence potentially involving practices in the US.
"I would like to know whether any of the evidence you are reviewing suggests that these unethical and sometimes illegal business practices occurred in the United States or involved US citizens," Rockefeller wrote in the letter sent on Wednesday.
News Corp, a publicly-traded company with headquarters in New York, has insisted that malpractice was confined to the UK, but a leading lawyer is currently looking into bringing cases against the firm on behalf of people who believe their phones may have been hacked while on US soil.
